Testimonials 

As an elderly customer I have always found this firm courteous, helpful and knowledgeable. They go the extra mile to get a good result. Engineer Mark was kind and tidy, and I felt comfortable that he was doing a great job. 
 
Mrs Wheldon, Kelvedon - 12th October 2018 
Extremely impressed with the company from the very first telephone call to the office to the expediency of the work carried out, a new manifold ordered and installed within a week so the underfloor heating could be used. Previously quoted around one thousand pounds by another company but pleased to say total price under 3 hundred. A company that can be trusted and believes in old fashioned customer service. Will definitely recommend this company as nothing too much trouble. 
 
Ms Foster, Colchester - 12th October 2018 
A big THANK YOU to Lee for coming to my rescue twice and a third time installing my new underfloor heating system. 
I can’t praise AJS enough, a fantastic team of men. A special thank you to Carol in the office for keeping me informed of what was happening and times and dates of work that was being organised for me. 
It’s definitely a 10 out of 10 for AJS and all the guys and galls. 
Best Wishes Eva 
 
Miss Chapman, Holland on Sea - 4th October 2018 
I am writing this testimonial on behalf of my mum. Mum had her boiler serviced on the 28th September and again what a brilliant service . Mark came to do it and he was on time, very friendly, very helpful and very professional. I would recommend AJS to anyone and will certainly use them myself in the future if I need any work doing. So thank you once again.

Mr & Mrs Prior, Lawford - 23rd July 2018 
Our company is using AJS for the first time, on a development of 5 apartments, we have found the workmen to be punctual,professional,pleasant & polite, long may it continue. 
 
Clive Harwood - Director - Rose & Harwood Ltd - 21st April 2018 
AJS were called when a pressure problem within our boiler had led to a pipe splitting. Another local company were called first, who charged a ridiculous price to assess the problem and I just couldn’t trust them to fix the boiler for anything less than a small fortune. I replaced the pipe myself, but the pressure was still wrong. 
AJS are completely professional, honest and serviced the boiler fully for less than the previous company charged for simply looking at the problem! 
We will be using only them from now on. Great service. 
 
Tony, Colchester - 20th April 2018

Nothing is ever straight forward but the quality of a Company is when they can solve the problems in a quick and trustworthy manner 
My father in law is very vulnerable but have total confidence in theses guys. 
 
Mr Kearney, Colne Engaine - 21st March 2018 
I've used AJS heating and plumbing many times in the last five years and have found them without fail to be responsive, helpful and always willing to try and fit in to our timetable and arrangements. They certainly go the extra mile. There have been many occasions when an urgent matter has cropped up and their willingness to try and create a space in the diary to help us out is a source of considerable reassurance. 
Their skills and professionalism are as good as any we come across.

Clive Pougher, Colchester - 12th February 2018 
A J S have just removed a bath and replaced it with a new walk in shower there were a few technical issues with the installation but top plumber Simon took it in his stride and produced a great finish. He also fitted a water softener in the garage, the pipe work was a work of Art. He then replaced a damaged sink in the Kitchen and made a really nice job of it. Would like to thank Rob, Vanessa, Carol, Simon and all the other staff at AJS for their help. I would recommend this company to anybody who wants a 1ST CLASS JOB thanks once again Guys REGARDS ALEX

Paul & Dawn Hancock, Colchester - 9th February 2018 
I am delighted with the service I’ve received from AJS. From initial call out to my clanking elderly boiler (which they then managed to keep going for several weeks while I made up my mind which replacement system to opt for), to the superb advice and service they gave in specifying and delivering the new boiler, they have been exemplary. I had to be away on the day they could fit it and I was nervous about what I would come home to find, but you wouldn’t have known they had been in the building except that the house was warm, the water was hot and the new boiler was gleaming on the wall. 11/10 and I can’t recommend them highly enough.  
 
F Brown, Brightlingsea - 9th February 2018

Another fantastic job done by this company. Came to service mum''s boiler and asked if they wouldn't mind looking up in the attic for us as we thought their might be a leak but it turned out to be a problem with the roof.

Even to replacing a washer that was leaking that I didn't even know about. Neat and tidy work at a very reasonable price and friendly staff. (Keeping a steady supply of tea going helps!)

Mr C. Everitt - Colchester - 8th February 2017 
My Mum has just recently had a walk in show put in and I cannot recommend this company enough. We had to wait a while for them because they have been very busy especially leading up to Christmas. Mum was prepared to wait as she knew how good they were after putting in a new boiler for her back in September last year. I would definitely use them when I need anything doing in my house and will certainly be recommending them to family and friends. Thank you to the whole team from office to engineers.

East Links Residential Ltd, Colchester - 15th September 2016 
Following a protracted and very stressful purchase (7 months) we eventually got the keys to Mums new flat in Stanway on Tue 30 Aug 16. Mum wanted the outdated boiler and immersion hot water system replaced with a combi boiler having had an excellent Worcester system in her previous bungalow. My neighbour recommended AJS having recently had some work carried out by them. We contacted Rob who came and estimated the work required on Wed 31 Aug 16, advised that a Vaillant boiler would be more suitable and followed up with an email quote that evening. He then advised that AJS could start the work on Thu 01 Sep if we were content. We accepted their timeframe and Lee Turner and the team arrived promptly on Thursday morning to start; the job completing on Friday lunchtime to our complete satisfaction. Furthermore, Lee also installed a new gas tap within the flat, the original being some distance away on the ground floor, and a new more user friendly and accessible water stop cock in the airing cupboard. Finally, all controls were fully explained, all waste removed and the flat left in a very clean and tidy condition. We would most certainly recommend AJS to any prospective customers. Thank you very much and we look forward to a continued association with regard to annual boiler servicing etc. 
 
Liz Clewlow and Audrey Dean, Colchester - 5th September 2016

Would highly recommend to anyone considering using their services. 
 
Mr & Mrs Rusbridge - Gt. Holland - 29th April 2016 
Thanks for the excellent job your guys did replacing our boiler. At no extra cost, they replaced a TRV in one of the bedrooms which had a slow leak and also installed a drain-off valve on the hall radiator. They were tidy, made good around the new flue etc and hoovered up after themselves at the end of the job. Very impressed and will definitely be recommending you to others.

I take this opportunity to express my sincere thanks for your assistance in dealing with this matter. On recommendation I contacted Rob on his mobile where I left a message, he responded within the hour and understanding the urgency of my situation we meet on site out of hours the same evening. Having assessed my requirements he took the time to explain the options available after which I accepted his recommendations. Your quotation was received by email the following day that I accepted, a date and time for the work to be carried our was agreed shortly thereafter. Your engineer arrived promptly on this date, he was smart and polite. I directed him to the location leaving my mobile number should he need to contact me during his visit. On my return home the new boiler was up and running with everything left neat and tidy as if nobody had been there. Your invoice arrived promptly. The whole operation shows your professionalism and a credit to all involved, I thank you again for your assistance and will have no hesitation in recommending your services to others.

Mr & Mrs W. - Colchester - September 2014 
What a pleasure it was to do business with AJS Gas and Heating Services. They offered a competitive rate for replacing our boiler and for additional plumbing and heating requirements we had. The team were courteous, efficient and polite, from the initial phone contact to emails and through to the final installation. Instead of ‘just doing the job’ they took the time to consider and consult us on the best ways of completing the complex work we requested and as such the end result was better than we had expected. They worked solidly and cleared up as they went along. It was a rare treat to have the sort of service that was without fault and I would thoroughly recommend them to anyone.
